 I have done it after add -m32,and the old error was handled.But when I
compile l4 again , there is another error :

---------------------------------------
I come across the stack problem last week when I reinstall
grub-0.97-os.7,and handle it by add CFLAGS=-fno-stack-protector.So I think
it's the same question,and add
CFLAGS =-fno-stack-protector in pkg/ipcmon/server/src/Makefile
but the problem cann't be handled.
Could you please give some advice?
much thanks!
